Vaginal Cytology and Male Repro Cytology Flashcards
(36 cards)
4 Vaginal epithelial cells
- Basal
- Parabasal
- Intermediate
- Superficial
4 Stages of Estrous
- Proestrus
- Estrus
- Diestrus
- Anestrus
Average age of occurence of vaginal neoplasias
10 yrs
The most common form of reproductive neoplasia
Mammary tumors
Vaginitis occurs regardless of
age, breed, repro status
Oldest vaginal epithelial cells that may or may not have a nucleus
Superficial
Youngest vaginal epithelial cells
Basal
Which part of estrous cycle where the female is attractive to the male but wont stand for breeding?
Lots of RBCs are seen on smear
Proestrus
Which stage of estrous is when females will seek out males and stand for breeding?
90% of fully cornified superficial cells and bacteria
Estrus
Which stage of estrus is where the corpora lutea are present?
Increase in progesterone
Diestrus
Which stage of estrus is the prolonged period of sexual rest?
Minimal secretions, cervix is tightly constricted, and vaginal mucosa is pale
Anestrus
This occurs regardless of age,breed, or repro status
Secondary to vaginal anomalies
C/S: mucoid to purulent discharge, pollakuria, and licking of the vulva
Vaginitis
2nd most common form of reproductive neoplasia
Vaginal Neoplasia
Average age of occurrence of vaginal neoplasia
10 yrs
Procedure for collecting Female sample (4 steps)
- Part lips of the vulva, insert swab at steep 90 degree angle
- After 1-2 in, alter the angle to 45 degrees
- When swab is fully inserted, rotate 2-3 turns
- Gently withdraw
To prepare a vaginal cytology smear, you should _______ the sample on to the slide
roll
Cytologic values for Proestrus
Superficial cells are predominate Non-degen neutrophils Parabasal Intermediate Bacteria
If bred within a day of preparing a vaginal smear, what may be seen?
Sperm
Cytologic values for Estrus
90% superficial
<5% parabasal and intermediate
bacteria
Cytologic values for Diestrus
Superficial cells decrease by 20%
Intermediate cells increase
Cytologic values for Anestrus
Parabasals and intermediate cells
Low neutrophils and RBCs
Semen collection technique (6 steps)
- Grasp prepuce, and push back to expose the tip of penis
- Slide collection cone over the penis and push prepuce down to expose the bulbis glandis
- Lock fingers in a ring around penis and hold the bulbis glandis in fist
- Apply pressure with forward and backward movement (male may thrust on his own)
- Watch for semen flow into collection tube
- Continue to apply pressure until fluid is crystal clear flows into collection tube
Collection method where a female in estrus expedites semen collection
Teaser Female
Collection method to obtain semen from cattle, horses, sheep, goats, rabbits, and cats
Male mounts the female and penis is diverted into AV
Artificial vagina
